An ideal fluid of density 800kgm
–3, flows smoothly through a bent pipe (as shown in figure) that tapers in cross-sectional area from a to
\(\frac{a}{2}\). The pressure difference between the wide and narrow sections of pipe is 4100 Pa. At wider section, the velocity of fluid is
\(\frac{\sqrt{x}}{6}\) ms
1 for x=_______. (Given g=10 ms
-2)
